I am using bootstrap select plugin to generate custom dropdowns in one of my projects but I am stuck in a very critical issue. The dropdown list is big and when dropdown is opened the screen moves/scrolls toward bottom a bit so that first few options can't be seen.
Issue can be seen here in this video:

And if you want to play around please check here the color filter:

Important: I can not use the max-height or add a scrollbar to it for fixing, I must display it without scrollbar. Please anyone can help?
If I understand you correctly, the solution is for whatever reasons NOT a scrollbar, but you want the first entries of your dropdown list to stay in view, right?
Maybe JS scrollIntoView() may help: If you have the chance to apply a class to your first list entry, you could use scrollIntoView when the list opens (which is normally the case at getting the focus or on click).
You can find a short description of scrollIntoView on this page: https://www.w3schools.com/jsref/met_element_scrollintoview.asp

I have a strange behavior with drop down lists and button in my layout.
I have just made a fiddle here to illustrate how this looks like.
As you can see in the example, if you resize the browser the you can still open the lists or click on the Filter button which is ok.
When I do the same on my desktop, the first list will work properly, but the second and third list will not open as well the button in not clickable anymore.
I have spent the all day trying to fix this issue, unfortunately with no success at all.
Maybe someone of you guys have had the same issue or knows what is going on here?
Any help will be much appreciated.
I've encountered issue like that before when wrapper elements were stretching over other elements via zindex and couldn't track it down until i gave each element a background color and could see how they were transforming in size as i adjusted the window size.
I am trying to perform a scrolling effect.
On scroll, the next page section should cover the current one.
So the current section is docked to the top of the screen and while the next section arrives the current is progressively covered but doesn't move.
Basically I am trying to reproduce the effect I found on this website:
http://www.squarespace.com/seven/interface
It works only with css (I tried with js disabled)
I've tried to reverse engineer it but I am not successful so far.
If someone had so advices I would greatly appreciate.
Main idea is that every <section> has height and position: relative and 'overflow: hidden'. But every tag inside those sections has position: fixed.
I tried looking at the site with JavaScript turned off and got nothing but a blank screen and a scroll bar (same in Chrome, Firefox, and Safari/iOS). Furthermore, Chrome tells me that all kinds of functions get called as you scroll. Unless there is some serious trickery here, squarespace.com seems to be using JavaScript.
Though you may be able to pull of something like the checkbox-hack to set and/or animate the top of different sections, I don't think the result for the minority of users validates the development time.
I put together a small fiddle which should help you on your way if you want something like the website you linked to. Notice that this is still usable if you disable or comment out the JavaScript.

A common problem I run into when building responsive websites is how to make a multi-level nav menu (3 or more levels) that works well for touch devices. I've seen a lot of plugins and techniques, but most of them fall flat because they don't allow a 2nd-level page to act as both a link to a page AND a parent of children in a sub-sub-menu. Some techniques address this by having an arrow icon that exposes the children menu items while clicking on the parent page name goes to the actual page... but on mobile devices these icons are usually very small targets and hence hard to use. Are there any other solutions to this problem (either jquery or javascript plugins, or straight-up CSS/JS code)?
I have a 'starting point' of sorts that I use for responsive web projects like this. I'm not sure if it's exactly what you need, but it allows for multi-level dropdown menus in desktop view. In mobile view, jQuery automatically creates an off-canvas menu.

Have you checked out any of the documentation surrounding touch-start events? I feel like you're going to get the best ux from this method. In your position, I'd be using tap to toggle classes onto your menu that would set the display to block (for example). Once your menu is open, you could then bind another touch event to the sub-level objects.
After our discussion in comments, it seems there isn't a straight forward way to get what you want due to the fact that we don't know what the user want after the submenu has been opened. There is no way for us to tell if they want to go to a link by clicking on the item again or collapse the submenu.
From this point, you have 2 options
Create a collapse once the menu is open and the user will know to use that to collapse the menu. If you think the size on most sites are small then make it bigger, however I don't think this will be an issue because it is so common.
Create a close button or something close to that for the entire menu. So when you click an item, it will expand, and if you click the same item again, it will go to the link. However there is collapsing the submenu until you click on the overall close button for the entire menu. This is only for tablets/phones as on desktop this should be a hover behaviour. This is similar to how the menu behaves on a tablet for http://www.lexus.ca. We actually have the menu closing if you click on the top most item again, you can see this behaviour on the phone or tablet. This is another option for you if the top level navs does not lead to pages.

I am using twitter bootstrap and has a very long page that I divide into multiple sections.
I'd like to implement a Section Indicator on top left of the screen that always shows where the reader is currently reading, like the screenshot below:
I managed to get the layout correctly as shown here:
However, I've got some problems that I've been working for a few weeks but still can't solved:
How to mark the current section dynamically as the user scroll
How to animate the movement of the arrow from the source to the next (or directly to the destination if the reader click a farther away rather than scrolling)
I've tried with the simpler version from getbootstrap.com/components but still to no avail... Please help... this is very stressful as I'm particularly weak in javascript and css :(
EDIT:
To summarize the answer:
Take a look at this library:
https://github.com/davist11/jQuery-One-Page-Nav.git
For a single-page website have a look at the One Page Navigation Plugin http://trevordavis.net/blog/jquery-one-page-navigation-plugin. It assigns a css-class to the current menu item upon clicking and as the user scrolls down the page.
So I have a drop down (select) element. The problem is that if there is a long list in it, then it "drops" upwards instead of downwards.
Is there a way to say that it should scroll rather than show all of them at once?
I know there's "size" but that's how many are visible at once (I only want one visible, like normal)
Or is the reason it's not having a scrollbar automatically caused by it's containing div? Does it need to know where it should end or something?
The way this works is up to the browser. Nothing you can do about it, other than building your own drop-down with JS.
The problem is not the list size, it drops upwards or downwards according the size above or below to always show the entire list if possible. It's a comprehensive behaviour and I don't think (and I don't want) you can change it.
